  <p>This process can be done in three different stages, according 

    to the tabs at the top zone:</p>

<ol>

  <li><b>Heading:</b> <br><br>

    The DataSet's heading contains information about this content: attributes, types, 

    rank of values, etc. All the information is defined from user's interface 

    in a simply way, because user only need to introduce the name of the DataSet 

    or Relation, and then repeat this steps until it's necessary: 

    <ol><br>

      <li>Introduce the attribute name.</li>

      <li>Select the attribute's type. If the type is &quot;Integer&quot; or &quot;Real&quot; 

        you must indicate the rank of values allowed. However, if the type is &quot;Nominal&quot;, 

        you must fill the list with the correct values.</li>

      <li>You must specify the attribute function.</li>

    </ol><br>

    Using the 'Add' button, the attribute defined is added to the DataSet's heading. You can remove an attribute from the heading by using the 'Remove' button.<br><br>

    <div align="center"><img src="imag/data_newProp.jpg"></div></li><br>

  <li><b>Data:</b><br><br>

    At this screen, you must fill the content of the DataSet. There is two ways for doing it, typeing 

    all the data (data must be separated by comas) or importing a 

    file containing them. <br><br>
    
		<div align="center"><img src="imag/data_newData.jpg"></div></li><br>

  <li><b>Save:</b><br><br>

    If you have defined the heading and filled the content of the DataSet, now you only need to Save the new DataSet in a file. At this stage, the content of the DataSet is validated 

    according to the heading, and if an error is detected, a message is shown.</li><br><br>
